Specification of Letters Patent.

I Patented Mar. 1, 1910.

Application filed September 16, 1908. Serial No. 453,323-

To all whom it may concern:

. Be it known that I, ALBERT W'ANNER, J12, a citizen of the United States, residing in Hoboken, Hudson county, New Jersey, have invented a certain new and useful Improvement in Chairs; and I do hereby declare the following to be a full, clea r and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying-drawings, and to letters of reference marked thereon, which fornra part of this specification.-

"lhis invention relates to chairs and particularly to bent-wood chairs having, in-' stead of the usual ring-brace for supporting the legs, a brace of the type shown in my U. S. Letters Patent No. 819,478, the object being to strengthen the chair generally and reinforce the backslegs in particular, especially against the tendency to loosen from the seat or break under sidewise or twisting strains. The invention is not limited in its application to chairs of the kind particularly set forth above, however, being applicable also to other types of chairs, as will be obvious.

trated The invention will be found fully illusin the accompanying drawings, wherein,

Figure l is a perspective view of one form of the improvedchair as seen from the rear thereof; Fig. taken in the plane of the joint between one of thebackdegs and the lower end of the structure forming the back and back-leg brace; Fig. 3 is a rear view of another form of the improved chair, the same having in this instance the ordinary ring-brace supporting its legs; Fig. 4 is a perspective view of a chair illustrating a modification of the invention; and, Fig. 5. is a similar view illustrating another odification.

Referring, first, to Figs. 1 and 2, the chair comprises the seat a, the front-legs I), and the bent-wood back and back-leg structure 0, the same being secured together in the usual .manner the chair also comprises a brace d in the form of a single (preferably) piece of wood secured to the front le s, seat and backlegs and so bent as to pro ace the substantially straight middle portion a, connecting the front legs, and the upwardly arched endpo'rtionsf, each connecting a front and a back leg and bearing against the under side of the seat.

2 is a cross-sectional view i i i i In carrying out my invention I provide a bracmgstructure which takes against the back-legs below the seat and rigidly sus-- tains them against movement toward each other, said structurehaving a substantially straigl'it form in side elevation; said'structurc may in some instances be alsoadapted to sustain the back and back leg structure against movement rclativctv to the seat. In the figures of the drawings now being refcrrcd to, this brace or bracing structure} in the form of of bout-wood y in the an inverted-U having stantially upright and shape, generall v,- of its extremities suln bcmg'bent first inward-ly towardrach other, as at 11, and then flaring, as at 2'. secured in the the chair-back. further secured, ot' the seat a which may be doweled (Fig. 2) to receivc said ends. The brace 7 being secured atits lower cnds to the baclclegs below the seat and in its upper back,

At the top of the brace it is usual manner to the top or as at the extremities are as by screws iv, to the back and being further, in the present instance, rigidlysccurcd to the seat, the baclvare supported against movement toward each other as well as against movcment relatively to the scat. thus iiii nirtilig to the chair as a whole perfect rigidity and insuring it againstits parts working loose through sidcwisc or twisting strains.

In Fig. 3 substantially the same form of brace is shown as applied to chair of the well known type legs are braced by means of The extremities of the brace m, which is a counterpartof the brace 1 may be secured, as shown, to both the seat and the ring brace, or either of them, and it has its ends dowin which the a ring brace 7.

clcd into the back-legs and'secured thereto 111 a plane below Fig. 1.-.

In Fig. 4, a bracing structure 11 is shown which comprises the U-shaped bent-wood member 0 and the cross-piecep; the member 0 is secured at its top to the top of the back and it has its extremities dowcled into or othcrwise secured to the cross-piece, which latt'cr is arranged belowthe seat g of the chair and is d'owclcd into the legs 1* or otherwise secured thereto.

In Fig. 5 the bracing structure comprises the parallel.membcrs 0r spindles s and the cross-piece t, the members .9 being secured at the seat, the same as in a single (preferably) piece and, at their ends, to the legs,'

8O portion to the top of the their upper ends to th'e top .piece dot. the

back not the chair and at their lower ends being secured to the cross-piece t, which is disposed below the seat 'w and connectsthe back-legs a, being doweled into or otherwise secured to thesame.

It will be observed that in Figs. as in-Fig. 1, the back-legs being rigidly held against movement toward each other at a point below the seat, the chair is strengthened and reinforced in the same respect as that shown in Fig. 1.

I make no specific claim herein to the construction shown in Figs. i and 5, the same having been made the subject matter of a divisional application, Serial No. 476101.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination, with a chair having a seat, a back, back-legs and front legs, of a bracing structure having a substantiallystraight form in side elevation and attached to the back. above the seat and also attached to the back-legs below the seat and holdin said back-legs against movement toward each other, substantially as described.

The combination, with a chair having a seat, a back, back-legs and front legs, of a bracing structure having a substantially straight form in side elevation and attached to the back above the seat-and also attached to the back-legs below the seat and bearing against the seat, substantially as described.

. 3.-The combination, with a chair having a seat, a back, back-legs and front legs, of a bracing structure having a substantially straight form in side elevation and attached to the back above the seat and also attached to the back-legs below the seat and being also attachedto the seat, substantially as de scribed. I

42 The combination, with a chair having a seat, an arched back and back-legs, of an inverted substantially U-shaped bracehaving a substantially straight form in side elevation and secured to the back above the seat and extendin and secured below said seat to the back legs, said brace standin clear of both side portions of the back and 3, tand 5,

stantially as described.

5. The-combination, with a chair havin a seat, a back and back-legs, of an inverte substantially U-sha ed brace having a substantially straight orm in side elevation and secured to the seat and to the back above the seat and extendin and secured below said seat to the back scribed.

the front legs, the back and back-leg structure, and a substantially U-shaped brace secured to the back and back-leg structure "above the seat and also secured to the seat and havin its lower ends dlverging and secured to t e leg-portions of said back and back-leg structure below the seat, substantially'as described.

7. The combination, with a chair having a seat, a back and back-1e s, of a brace having a substantially straight orrn in side elevation and comprising downwardly projecting substantially upright portions, said brace being seeuredto the back above the seat and each of its downwardly projecting portions extending'from' above theseat to a bacleleg below the seat and being secured to the latter below the seat-, substantially as de- I have hereunto set my hand this 14th day of September, 1908'.
